WALTER STEINMANN, F BLOOMFIELD, NEW JERSEY GLUING MACHINE Application filed August 17, 1929. Serial No. 386,617.

In the preparation of books for binding it is the practice to assemble the component parts or signatures, whether single pages or groups of pages, jog them at the1r edges to 6 properly even them, and then to apply glue to the backs to fasten such signatures together and prepare the backs for the posslble application of a backing strip of paper, muslin or other material. This application of glue has been by manual operation of a brush ulation of the amount of glue supplied to the backs and an even distribution thereof withmachine is shown in the drawings, in which Fig. 1 is a plan view and Fig. 2 a longitudinal or side elevation in partialsection. In these drawings the machine is shown as carried by, or mounted upon, a suitable table 1 having a movabletop 2 hinged thereto, as at 3, to permit accessto certain parts for cleaning, ad-I justment, replacement or repair.

The tablecarries two compartments, 4 and 5, serving as glue-pot and water-pot respectively. Each pot preferably contains an electric heater 6 for maintaining the glue at the proper consistency on the one hand and creating vapor on the other hand to soften the brushes (presently to be described) and keep them from accumulating an undesired amount of glue. I

In the glue-pot 4 is partially immersed a metal roller? with smooth surface, rotatably supported .in suitable bearings, and power driven. In juxtaposition to the metal roller 7 is an adjustable scraper 8 for the regulation of the amount of glue carried by the roller 7. The upper surface ofthe roller 7 projects upwardly through an opening in the table top out smearing with glue the top or bottom. edges of the book. .My preferred form of such 2, so that the backs of books may be brought in contact with the roller, as will later be fully pointed out. 1

Mounted in the water-pot 5,fpreferably above the level of the water therein, are'two 5 rotatable, cylindrical brushes 9 and 10, preferably made in sections so spaced aslto permit the bristles to project up between'the wires of a grille 11; the extent of-such pro- 1 j ection is regulated or determined by the 'vertical'adjustment of the wire-supporting bars 12 on their posts 18, carried by the table-top 2, and movable therewith. The brushes9 and 10 are geared or belted, or otherwise'driven, so as to rotate in opposite directions, the right-hand brush 9 rotating clockwisefand the left-hand brush 10 rotating c'ounter-clocka wise; thespeed of the brush 10 is preferably. greater than that of the brush 9, for a purpose presently to be described.

At the right end of the grille 11 is a guide plate 14, adjustable longitudinally, as at 15, to guide thebook or group of books A into position to be acted upon by the brush 9; at the left end of the grille 11 is a'stop-plate 16, adjustably mounted on the table-top 2, as at 17 to limit the movement of the book or gipup' of books toward the left, as shown at 'lhe brassroller 7 and the rotary brushes 9-10, are preferably driven by powerfrom a shaft 18, such shaft itself being preferably driven from'an electric motor 19 or other source of power; in the present instance the motor 19 and the shaft 18 are shown as mounted on or carried by the table 1., 'The brush 9 is shown with its driving belt twisted to get the reversal of direction of brush 9with respect to brush 10; as will be seen from the relative sizes of driving pulleys on brushes 9 and 10,- the brush 10 rotates faster than brush 9 to compensate for the fact that the beoks are themselves moved from right to le t.

In the operation ofthe machine the operator takes an assembled set of signatures oomprisinga' book, orseveral such assemblies if he can grasp "them in his two'hands, and jogs the edges to even them. He then passes the backs over the glue roller 7 taking care that ion the front edge of the backs Without? smear-- ing the forward vertical faces of the. books; the proper adjustment of the stop 16 preventsthe. brush 1.0.; from. wiping any glue. on; the; vertical rear faces of. the books It will be noted that the adjustment of the guide? plate. 1 4;. gives an. initial-.positioning A- of: the bookswith the-front edges in advanceof. the brush 8, so, that the brush9k doesnot smear the verticaLfrontfaces. v

above the brushes between the members of which the bristles of such brushes emerge, a guide plate at one end ofthe grille along which the book passes, such book having had glue previously applied along the major portion of the back while leaving the ends of the book free of glue, said guide plate being so positioned with respect to the first brush as to make such brush contact with the book back of the forward edge thereof, to distribute the glue toward the back edges and a stopplate at the other end of the grille so positioned with respect to the second brush as to prevent such second brush from contacting with the rear end of the book while distributing the glue toward the forward end thereof.
